이 연구의 목적은 경도 정신지체아동의 학습된 무력감을 감소시키기 위하여 체계적인 귀인훈련를 적용함으로써 학업성취능력과 학습태도 개선에 미치는 영향을 밝히는데 있다. 연구대상은 개인용 지능검사 결과 IQ 60-75사이이고 초등학교 특수학급에서 시간제 특수교육을 받고 있는 이동 3 명으로서 신체 및 언어장애와 같은 심한 장애가 없는 아동이다. 연구결과, 귀인훈련이 오랜 학교학습상황에서 겪게 된 학습의 실패상황에서 실패원인을 「능력」에 귀인하는 아동을 「노력」 에 귀인하도록 힘으로써 아동의 「학습된 무력감」 를 감소시키는데 효과적임이 밝려졌다. 즉,뺄셈학습과제의 수행속도가 귀인훈련 후 빨라졌으며 과제에 대한 흥미도 많이 증가하였다. 또한 귀인훈련이 경도 정신지체 아동의 학습태도를 개선하였다. 귀인훈련 후 아동의 실패과제에 대한 지속시간이 많이 늘어났으며, 아울러 실패과제에 대한 불안행동이 많이 감소하였고, 주의집중이 향상되며 학습태도가 바람직히게 변화된 것으로 나타났다. 이 결과는 귀인훈련을 통해 경도 정신지체아동의 학업성취도와 학습태도에 긍정적인 변화를 가져올 수 있음이 확인되었다. The purpose of the present study is to investigate how systematic atributional training affects leaming achievements and leaming attitudes for the children with mild mental retardation through decreasing their feelings of learned helplessness. For the study, three children with mental retardation, whose 1Qs range from 60 to 75, were selected from those who were enrolled at special classes of elementary schools. They do not have physical handicapped and language problems. The procedure applied to this study focused on the changes the reason for the learning failure from "their ability" to "their lack of effort".

臨床에서 慢性的인 退行性 筋骨格系 疾患에 頻用하는 獨活寄生湯의 實驗的 效能을 糾明하기 위해 本 論文에서는 筋骨格系의 機轉에 臟腑의 肝과 腎이 어느 정도 영향을 미친다는 韓醫學의 基礎理論에 根據하였다. 獨活寄生湯의 煎湯液을 흰쥐에서 服用시킨 후 臨床病理上 肝과 腎의 機能에 관련이 있다고 판단되는 血淸中 creatine BUN total protein albumine total cholesterol의 含量 變化를 測定 觀察하였다. 筋收縮에 주요한 에너지원이 되는 creatine은 筋肉의 崩壞와 萎縮을 일으키는 筋疾患에 있어서 上昇하며 평소 尿中에는 거의 나타나지 않은 cretine의 增加는 筋疾患診斷에 상당한 意義가 있다. 獨活寄生湯의 濃度를 1,5,10%로 하여 5,10,15일간 投與한 후 血淸中 cretine의 含量變化를 觀察하였더니 有意性있는 저하를 보였다. This experimental study was designed to investigate the effect of Dokwhalgisaengtang on the production of BUN, creatine, total protein, albumin, total cholesterol of the rat serum. The results are follows : Dokwhalgisaengtang extract decreased the serum BUN significantly in rat Dokwhalgisaengtang extract decreased the serum creatine significantly in rat . Dokwhalgisaengtang extract decreased the serum total protein significantly in rat. Based on the results, it is concluded that the clinical application of Dokwhalgisaengtang can help to treat muscle weakness.

Masan bay is one of the polluted enclosed bays, which has red tides problem and the formation of oxygen deficient water in the bottom layer. Most important factors that cause eutrophication and red tide is nutrient materials containing nitrogen and phosphorus which stem from terrestrial sources and nutrients released from sediment. Therefore, to improve of water quality, reduction of these nutrient loads should be indispensible. At this study, the three-dimensional numerical hydrodynamic and eutrophication model, which were developed by Institute for Resources and Environment of Japan, were applied to analyze the processes affecting the phytoplankton production and also to evaluate the effect of water quality improvement plans on phytoplankton production. in field survey, the range of concentrations of chlorophyll -a at surface area was found to be 29.17 - 212.5㎎/㎥, which were exceeding eutrophication criteria. The constant currents defined by integrating the simulated tidal currents over 1 tidal cycle showed the counterclockwise eddies in the southern part of Budo. The general directions of constant currents were found to be southward at surface and northward at bottom over all the bay. The eutrophicatior model was calibrated with the data surveyed in the field of the study area in June, 1993 The calculated results are in fairly good agreement with the observed values within relative error of 30%. The pollutantI load from the sources such as the input from terrestrial sources and release from the sediment was reduced by the rate of 50, 70, 90, 98% to evaluate the effect of phytoplankeon production. Phytoplankton production was reduced to 50% in case of the 90% reduction of the input loads from terrestrial sources and 8% in case of the 90% reduction of the load from sediment.

CNU56, CNU112 계통에서 가장 많았고 대조품종과 CNU 128 계통에서 10개 미만으로 가장 적게 나타났다. 3. 수장은 육성 계통 중 CNU88 계통에서 가장 길었으나 대조구보다 짧고, 육성계통 중에서는 CNU 126 계통이 가장 짧았다. 4. 주당 영화수는 대조구인 동진벼보다 CNU50 계통에서 2배 이상 많았고, CNU158 계통에서 가장 적게 나타났다. 5. 천립중은 CNU113 계통에서 30g이상으로 대조구와 같이 가장 무거웠고, CNU128 계통에서 20g으로 가장 적었다. 6. 주당 수량은 대조구의 26.6g에 비해 CNU50, CNU112 계통에서 두배정도 높았고, CNU128, CNU158, CNU200 계통에서 가장 낮게 타나났다. Aims of this study were carried out to develop the useful lines induced from mutation and pedigree breeding methods among the collected genetic resources from national and domestic areas. In this study, Stem height of CNU126 line and check among them were high, while CNU128 was lower than other lines. Spiklet length of CNU88 was longer, but that of CNU126 was shorter than check. Number of spiklets per plant of CNU50 among lines have twice time than check. 1,000 grains weight of CNU113 was higher than check. In yield per plant, CNU50 and CNU112 were higher than check, Dongjinbyeo.

韓炳九,李光宰,李京子 慶熙大學校 1987 論文集 Vol.16 No.-

The Purpose of this research is to investigate the role of communication in the political behavior of college students in Korea. The relationships between the communication patterns of college students, and their political knowledge, political orientation and political activities were examined. 700 samples were randomly selected among the students of seven colleges; four universities in Seoul area and three in rural areas. It was found that: 1. All communication media affected the political behavior of college students. 2. The direction of the influence was mostly negative to the orientation toward the subjects. 3. Especially, the irregular communication media(Dae Ja Bo. printed matters, and rumor) strongly affected the political orientation and the political activities of college students. It is suggested that the activation of the existing media with more freedom of press are necessary to minimize the unhealthy impact of the irregular communication media upon the large number of audience.

In patients with unilateral condylar hyperplasia, increased length of the condylar neck causes deviation of the mandible to the opposite site, resulting in facial asymmetry, but the arch form and general contour of the displaced mandible is approximately symmetric. So, the unilateral condylectomy have been prefered surgical method among the surgeons. The purpose of this study is to analyze the postoperative results comparatively following two different surgical methods, condylectomy and ramus surgery, in unilateral condylar hyperplasia. Case of 6 patients with the unilateral condylar hyerplasia were analyzed in this study, 3 case of the condylectomy only, 3 cases of the ramus surgery, Clinical and radiographic evaluations were tried for comparison. In conclusion, comparative results between two groups did not show any significant difference,but we confirmed that unilateral condylectomy could be a excellent surgical methods in unilateral condylar hyperplasia thinking over the unique morphological characteristics of it.

여광응,추연구,김정선 국립특수교육원 2002 특수교육연구 Vol.9 No.1

국·공립 정신지체학교 중 유, 초, 중, 고 복합과정 단일장애학교 25개교를 대상으로 형식적 교육목표 설정에 관한 실태조사를 실시하여 竹田의 「형식적 교육목표」분류표를 중심으로 학교교육목표와 과정별 교육목표를 분석 검토하였다. 그 결과 각 학교의 학교교육목표들은 「형식적 교육목표」항목 중 「시민행동」과 「관계와 조건에 의한 강화」, 「운동·건강」순으로 언급을 나타내었고, 과정별 교육목표에 있어서는 유치원 과정에서는 「신체적 표현」, 「도구사용 방법」, 「운동·건강」, 「상징 언어행동」, 중학부과정에서는 「약속」, 「시민행동」, 「운동·건강」과 「직업행동」, 고등부 과정에서는 「약속」, 「직업행동」「음에 의한 노래」등의 순으로 나타났다. 이러한 결과를 종합해 보면, 많은 정신지체학교에서 기르고자 하는 인간상으로는 「건강하고, 자주적인 사람으로 길러 기능인으로 자립하여 도덕적인 생활인을 기른다」는 바램이 교육목표로 설정되고 있음을 알 수 있다. A survey was conducted on the formal education objectives of 25 public special schools with composite courses of pre-school, elementary, and middle and high school for children with single mental retardation, and the survey results were analyzed by school education and course education objective according to the Taketa's classification of 'formal education objectives'. In the surveyed school education objectives, the most mentioned items were in the order of : Civil Behavior, Improvement by Daily Routine, and Exercise and Health. In the course education objective, the most mentioned item in the pre-school course was Physical Expression to be followed by Use of Tools and Engagement. In the elementary school course, was in Use of Tools, Exercise and Health, and Symbolic Language Behavior regular order. In the middle school course, it was in the order of Engagement, Civil Behavior, and Exercise and Health, In the high school course, it was revealed Engagement, Career Behavior and Song by the Sound in order. Putting these results together, it can be said that many special schools for the mentally retarded children aim to raise the children as 'healthy, polite and independent inhabitant who can lead their own living.
